If only for the BFI warning that comes with this movie - "this film contains scenes that some viewers may find offensive" - this has got to be recommended. This "very definitio of schlock" also screens on 12 June. More details here.
Chicago Reader review:
A 98-pound weakling falls into a tub of toxic waste and emerges as a superhero; the first order of business is revenge on all the creeps who picked on him earlier. Cruddy, primal, extremely violent, and fairly entertaining, this 1984 feature from the New York-based exploitation outfit Troma, Inc. (Lloyd Kaufman and Michael Herz) captures some of the snot-flicking spirit of the old EC comics. How much you'll enjoy its deliberate crudity probably depends on how far you can let yourself regress to surly adolescence.
Here (and above) is the trailer.
